Application file November 16, 1903. Serial No. 181.418.

Be it known that], ALFRED HUTOM Rown, a citizen of the United States,residing at Donaldson, in the county of Kittson and State of.\lini'1esota, have invented a new and useful hurn, of which thefollowing is a specification.

This invention relates to churns, and has for its object to produce adevice of this character of simple ctmstruction, easily operated andcleaned, and which will operate effectively with the expenditure of alimited amount of labor; and the invention consists in certain novelfeatures of construction, as hereinafter shown and described, andspecified in the claims.

In the drawings illustrative of the invention, in which correspondingparts are denoted by like designating characters, Figure 1 is asectional side elevation. 2 is a transverse section on the line 2 2 ofFigl. Fig. 3 is a transverse section on the line 3 3 of Fig. 1. Fig. 4:is an enlarged detail plan of a portion of one of the dasher-armsdetached.

The improved churn construction comprises a base or platform l0, uponwhich the creamreceptacle 1.1 is supported and which also supports aframework [2, carrying a d rive-shaft 13, having an operating-crank 14:and gearwheel 15.

The cover of the receptacle is represented at u; and the dasher-rod at17, the latter extending through the cover and supported for rotation bya bearing from the frame 12 and carrying a gear-pinion [8 for engagementby the gear 15, as shown.

The support for the dasher-rod consists of a bar 19, secured betweenbrackets 20 21 on i the framework 12 and having a half-bearing for therod 17, and a cap-bar 22, supported detachably, as by pins 23 2%,between the brackets, as shown, one or both of the pins being detachableto provide for the removal of the dasher-rod when required.

\Vithin the receptacle 11 is a base-frame 25, formed of one or moretransverse bars and preferably spaced from the bottom of the receptacleby a spacer-block 26, as shown.

The base-frame is composed of two meml bers crossing each other at rightangles, as shown, and to the outer extremity of each of the arms thusformed is secured a verticallydisposed rib 27, the lower end of which isextended downwardly, so as to give it a bearing upon the bottom of thereceptacle 11, while the upwardly-cxtending ends of said ribs aredisposed in close proximity to or against the inner wall of thechurn-body or receptacle 11, as shown.

Connected to the rod 17 above the frame 25 are one or more fiathorizontally-disposed arms 28, and vertically disposed through thesearms are a plurality of pins 29, spaced apart and arranged in parallelrows, the pins of one row disposed opposite the spaces between the pinsof the adjacent row, as shown.

Any desired number of the arms 28 may be employed, but generally twowill be sufiicient, as shown, and any number of the pins 29 may bedisposed in the arms and spaced any distance apart and as many of theparallel rows of pins used as may be desired or found efficient.

The rod 17 and pins 29 will preferably be of metal, galvanized orotherwise protected from corrosion, while the bars and 28 and the ribs27 will preferably be of wood.

The dasher and base-frame and its attached ribs are easily removablefrom the receptacle for cleaning, and every part with which the creamcomes in contact is thus easily accessible for that purpose.

By the construction and arrai'igei'nent of parts herein described itwill be seen that the frame which includes the cross-bars 25 and thevertical bars 27 is spaced above the bot- 1 tom of the cream-receptaclenot only by the lateral spacing member, but also by thedownward-extended ends of the bars 27. It follows that when the dasheris in motion the cream will be agitated in such a manner that a portionthereof will be broken against the edges of the bars 25, which arespaced above the bottom, as shown, while the pins, set staggered withrelation to each other in the dasherarms 28, will very eflicicntlyagitate the cream and cause the formation of butter-globules to takeplace very quickly, while the gathering of the butter will also befacilitated by the close and staggered relation of the pins 29 extendingthrough the dasher-arms in both an upward and an outward direction.

Having thus described the invention, what I claim is- 1. In a churn, thecombination of a creamreceptacle, a frame supported therein, said framecomprising two members crossing each other at right angles, a spacingmember interposed between said members at their points of intersectionwith the bottom of the receptacle, and uprights at the outer ends of thearms formed by the crossed, members, said uprights being extendeddownwardly to bear upon the bottom of the cream-receptacle and upwardlyin contact with the walls of the latter, said frame being thereby spacedabove the bottom of the churn; and a dasher stepped for rotation in saidframe, and concentrically of the uprights of the latter, said dashercomprising a central shaft, transverse, flat, horizontally-disposedarms, each having two or more rows of staggered perforations, and pinsextending vertically through said perforations.

2,. In a churn, a dasher composed of a plurality of flat bladesradiating from a central stem or staff, each of said blades beingprovided with a plurality of rows of perforations disposed in staggeringrelation to each other, and pins extending through said perforations andprojecting above and below the blades.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

ALFRED NUTOM ROWE.
